Continuity mistake: After Anakin and the most recently mutated Nelvaanian free the other mutated, the latter puts his hand on one of his fellow's shoulder. When he does, the control harness the two should have destroyed earlier is still on; in the next scene right after, the harness is gone.

Continuity mistake: When Mace Windu intercepts Grievous at the latter's gunship, Grievous activates his lightsabers while standing on the ramp to his ship's hatch. But when Windu crushes his chest and Grievous starts to cough, he is suddenly standing right inside the hatch.
